This paper is interleaved Fly-Back converter to operate gird-connected micro inverters have been studied. Solar energy is already the exhaustion of fossil fuels and environmental concerns have been many studies. In this paper, Grade 200W of electrical energy generated by solar modules used efficiently and Power conversion system for Grid-Connected aims to development. Low-cost, high efficiency inverter in order to realize Grid-Connected is needed other methods from traditional centralized inverter that is the configuration. Therefore soft switching ZVS operation possible two parallel interleaved Fly-Back DC/DC converter topology by configuring the input circuit, simple inverting output stage to match the power frequency to repeat an action in the form of a Pass-through DC/AC inverter is used. And Sine wave output current by controlling the operation with high efficiency was realized. Output current is sine wave and controlled to operate at high efficiency. This paper interleaving 200w operation and to calculate the maximum current, the output current is controlled to behave as a sine wave was described.
